About Converting Ounces per Milliliter to Pounds per Teaspoon
Ounce per Milliliter and Pound per Teaspoon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
pounds per teaspoon = ounces per milliliter × 0.308057599609
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per milliliter equals 28349.523125 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct ounce per milliliter-to-pound per teaspoon factor of 0.308057599609.
Simple example
1 oz/mL × 0.3080575996 = 0.3080575996 lb/tsp
1 ounce per milliliter = 0.3080575996 pounds per teaspoon.
Real-world example
1,000 oz/mL × 0.3080575996 = 308.0575996 lb/tsp
1,000 ounces per milliliter = 308.0575996 pounds per teaspoon.

Frequently asked questions
How many pounds per teaspoon are in 1 ounce per milliliter?
1 ounce per milliliter equals 0.3080575996 pounds per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per milliliter to pound per teaspoon?
Multiply the ounce per milliliter value by 0.3080575996. The converter above does this instantly to whatever precision you set.
How do I convert pound per teaspoon back to ounce per milliliter?
Use the reverse factor: 1 pound per teaspoon equals 3.246146179 ounces per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per milliliter?
Ounce per Milliliter (oz/mL) is a unit of density.
What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
Is the ounce per milliliter to pound per teaspoon conversion exact?
Yes. Both ounce per milliliter and pound per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.3080575996 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
